Compared to a similarly charged sphere, a charged conical conductor loses its charge due to

View answer and explanation

Correct option: B

Corona discharge.

Option B is correct because a charged conical conductor loses its charge primarily through corona discharge, which occurs at sharp points due to high electric field concentration.

The ratio of magnitude of electric displacement (D) and electric field (E) is Gauss’s Law is valid for In hydrogen like system the ratio of coulombian force and gravitational force between an electron and a proton is in the order of: Statement-1:

\overrightarrow{{E}}

in outside velocity of a conductor depends only on the local charge density

\alpha

.
Statement-2:

\overrightarrow{{E}}

in outside vicinity of a conductor is given by

\frac{\sigma}{\varepsilon_0}
